I guess all those fossiles were hide by sneaky scientists wanting to prove a point.

Extinction has nothing to do with Evolution, at least not in the way the Dinosaurs were said to have gone extinct.  

Two things.

1) The fossil record is one of the bodies of evidence that evolution is based on

2) Mass extinction events have heaps to do with evolution. Mass extinction empties a lot of biological niches - the extinction of the dinosaurs left all of the niches for large land fauna empty. Mammals filled the empty spots.
